PHARMACODYNAMIC
Pharmacological group: Progesteron antagonists.
ATC Code: G03XB01
Mifepristone is a synthetic steriod that acts a progesterone antagonists by competing with the receptor for endogenous progesteron receptors. Medicine binds very strongly to this receptor (2 to 10 times the progesteron). The emergency contraceptive mechanism of mifepristone includes:
  - Fertility  suppresses follicular function as well as suppresses the endocrine fuction of granulosa cells, so patients will be less likely to ovulate if given the drug before ovulation.
  - The drug breaks the peak of LH in the middle of the cycle, thus inhibiting ovulation.
  - If taken at the end of the cycle, the drug interrupts endometrial support by the hormone, creating an asynchronous cavity in the endometrium, leading the degeneration and peeling of the endothelial lining, which in turn prevents and inhibits the fetal attachments to the uterus.  
PHARMACOKINETICS
After oral administration, peak plasma concentrations of mifepristone were reached after 1.3 hours. About 70% availability. The elimination include two-phase, slow-phase  is followed by a faster phase with a half-life of about 18 hours. Mifepristone is metabolized by the liver, the metabolites are excreted in the bile and excreted in the feces. Ony a small amount of the drug is found in the urine. Mifepristone binds to plasma proteins about 98%, predominantly with α1-glycoprotein acid.

CAUTIONS AND RECOMMENDED WHEN TAKING MEDICINE
  - Emergency contraception is a emergency measure that can oly be used in emergencies and is not a substitute for regular contraception. People who use emergency contraception many times should consider using long-term contraception.
  - The method of emergency contraception can not achieve the desired effect in all cases. If you are not sure about the duration of unprotected sex of if woman has had an unprotected sex for more than 120 hours in the same menstrual cycle, you may be pregnant. Therefore, treatment with mifepristone 10 mg after second intercourse may not have a contraceptive effect.  If the menstrual period lasts more than 5 days,  or bleeding is unusual on the expected menstrual period or pregnancy is suspected for any other reason, the patient must be determined not to be pregnant.
  - Unprotected intercourse after treatment may increase the risk of unintended pregnancy.
  - Do not repeat the same cycle because it can cause menstrual disorders.
  - It should be used with caution in patients with less severe asthma or chronic obstructive pulmonary disease, hemorrhage, cardiovascular disease or related risk factors, anemia.
  - It should be used with caution in patients on long-term treatment with corticosteroids; Corticosteroids may be used if acute hyperplasis is suspected.
  - Caution should also be exercised in patients taking anticoagulants as it may increase the risk of severe bleeding.
PREGNANT
Do not use drugs for pregnant women and drugs do not have the effect of abortion.
A dose of 10 mg is not enough to cause a miscarriage, but it can not be excluded that bleeding may occur in some cases if the woman is pregnant.
Breast-feeding women
Mifepristone can be excreted in milk of mother. Because mifepristone effects on children are not known, breast-feeding women should consult a physician to decide whether to clear breast milk for few days after taking the drug.
Ability to drive and operate machines
Impact on the ability to drive and operate machines is unknown. In the case, patients with headaches should be careful when driving or operating machinery.
DRUG INTERACTIONS
Do not take aspirin and NSAID together with mifepristone because theoretically prostaglandin synthase inhibitors can alter the effect of mifepristone.
